As a temporary solution I have ordered the NA Solstice shop manual, however, I need the pin-outs on the GXP ECU, but, they are way different on the two models. I have heard other posters mention the on-line manual, is that accessible to everyone and is it available for the GXP. If any dealers see this post it might be nice to permanently post the table diagrams of the the ECU
One thing I found out these cars are not that easy to work on, they have access problems. I had to replace the factory oil pressure transducer with a new transducer for an oil gauge. I have figured out how to do it, but, at first I thought I had to pull the starter. When I looked up that procedure i found out you have to pull the intake manifold to pull the starter - whew.
